Conduction

Conduction is the process of heat or electricity being directly transferred through a substance from one particle to another, without any actual movement of the material itself. This occurs because of the collision of molecules or atoms. Thermal conduction refers specifically to the transfer of heat energy. Electrical conduction refers to the transfer of electrical charge, often through the movement of electrons. The rate of conduction depends on the material's properties, such as its thermal or electrical conductivity, as well as the temperature gradient or voltage difference.

Conduction meaning with examples

• The chef's hand recoiled as the metal pan, heated by the stove's flames, burned her hand. This painful experience was the result of thermal conduction, where heat energy transferred from the pan's hot surface to the cooler surface of her skin. The pan had good thermal conductivity.
• When the iron poker was placed in the fireplace, the end exposed to the flames quickly became red hot. The heat from the fire was transferred along the length of the poker via conduction, a process where kinetic energy is passed between atoms within the iron.
• The heating system utilized copper pipes because copper is known for its high thermal conduction, efficiently transporting the heat from the furnace to the radiators throughout the house. conduction is vital in home heating.
• Electric current flows through a wire because of electrical conduction. The flow of electrons, driven by the voltage difference, is the mechanism that powers our lights and appliances. Materials with high electrical conductivity facilitate this process.
• Touching a metal doorknob after rubbing your feet on a carpet can result in a shock due to electrical conduction. The built-up static electricity, a charge, rapidly discharges into the metal conductor, causing a spark.
